Patent CA-2046649-C (CA)
Inventor: STETLER-STEVENSON WILLIAM G
IPC: C07K14/81
Filed: 1990-03-21
Granted: 2007-06-12
Abstract: The present invention is an isolated protein of 21,600 daltons which binds to both latent and activated type IV collagenase with high affinity at 1:1 molar stoichiometry, thereby abolishing enzyme activity. The protein is purified by affinity chromatography on solid phase metalloproteinase, or solid phase metalloproteinase substrates which bind the enzyme-inhibitor complex. The complete primary structure of this protein (initially called CSC-21K), as determined by sequencing overlapping peptides spanning the entire protein, reveals homology with a protein called TIMP, Tissue Inhibitor of Metalloproteinases. In addition, a cDNA for this novel inhibitor, now designated TIMP-2, was cloned from a melanoma cell and its sequence was compared with that of human TIMP-1. Northern blots of melanoma cell mRNA showed two distinct transcripts of 0.9 kb and 3.5 kb which are down-regulated by transforming growth factor-beta, and are unchanged by phorbol ester treatment. The figure 7 shows the cDNA  and corresponding protein sequence of TIMP-2.

Abstract: Le mouvement d'horlogerie comprend un mécanisme à quantième perpétuel, un mécanisme â équation de temps, et un troisième mécanisme qui est actionné par le premier pour modifier la position angulaire d'une came d'équation de temps du second mécanisme, en fonction du nombre de jours des mois. Ainsi, cette came fait toujours exactement un tour complet en une année, quel que soit le nombre de jours de l'année. Le mouvement est donc à quantième perpétuel et à équation de temps perpétuelle. Il a aussi l'avantage qu'après un arrêt indéterminé, la remise automatique de la position angulaire exacte de la came d' équation de temps se fait sans erreur possible simplement en remettant en phase le quantième, l'année, le mois et l'heure.

Title: Improved nozzle for a plasma arc torch
Inventor: SANDERS NICHOLAS A
IPC: H05H1/34
Filed: 1990-07-20
Granted: 1995-12-05
Abstract: A plasma arc torch mounts an electrode and a nozzle, with a mutual spacing, symmetrically about a common longitudinal axis at one end of the torch adjacent a workpiece.  The inner surface of the nozzle has an annular, inwardly-directed projection, located opposite the electrode and at a point of closest spacing between the electrode and the nozzle.  The projection, or "angle kink", is characterized by a minimum radius of curvature as compared to the radii of curvature of adjacent portions of the nozzle opposite said electrode.  The inner surface is adjacent a central exit passage of the nozzle and the angle kink is spaced from the intersection of the exit port and the inner nozzle.  In the preferred form the interior nozzle surface is formed by two conical surfaces each having different slopes with respect to the longitudinal axis so as to form the circumferentially extending angle kink at their plane of intersection.

Title: Process for the preparation of cooking liquors having high sulphidity for sulphate pulp cooking
Inventor: HEDBLOM MATS-OLOV
IPC: D21C11/12
Filed: 1990-11-21
Granted: 2002-04-09
Abstract: An improvement is provided in a process for preparing, under reducing conditions, cooking liquors for sulphate pulp cooking. The black liquor which is formed in the cooking process is fed, after evaporation, completely or partly to a reactor operating at increased temperature. The increased temperature is obtained by energy which is supplied from an external heat source and/or release of energy from the black liquor, thereby to form a melt of sodium sulphide. The melt then is withdrawn to be further processed to cooking liquor. The melt, and the whole or part of at least one of sulphur-containing, sulphur-and sodium-containing materials which are present in the pulp mill including sulphur-containing, and sodium- and sulphur-containing make-up chemicals used for the total chemicals balance of the pulp mill, are fed to the reactor in such a way that the mole ratio of sodium to sulphur in the total mixture which is fed to the reactor is within the range of from 1.5 to 4.

Title: Optical fiber package and methods of making
Inventor: FRITZ DOUGLAS EDWARD
IPC: B65H55/04
Filed: 1992-05-25
Granted: 1998-06-30
Abstract: A package (20) Or wound optical fiber (22) includes a spool (23) on which are wound a plurality of layers with each layer comprising a plurality of convolutions of the optical fiber. The winding is accomplished such that each successive convolution is spaced from a preceding convolution. The spacing is such that on the third and further outer layers, each optical fiber is tangent to each of two adjacent convolutions of a previously wound layer and to one convolution of the next inner layer. Also, each convolution in each layer after an innermost layer crosses transversely optical fiber of an immediately preceeding layer in two relatively closely spaced locations and such that crossovers in successive layers are staggered circumferentially of a winding surface. Because of the nesting which is caused to occur, excellent density, package rigidity and stability are achieved. Further, winding abnormalities such as crossovers are substantially reduced, resulting in a package of optical fiber which exhibits very low loss due to winding.

Title: Single horizontal well conduction assisted steam drive process for removing viscous hydrocarbonaceous fluids
Inventor: LU HONG SHEH
IPC: E21B43/30
Filed: 1992-11-30
Granted: 2002-11-19
Abstract: A conduction assisted steam flooding process is described where heavy oil is recovered from reservoirs with limited native injectivity and a high water saturated bottom zone. A horizontal well is placed above the water saturated zone. This well is perforated on its top side at selected intervals. An uninsulated tubing having a circumference smaller than the well is inserted therein to its furthest end thereby making a first and second conduit. Steam is injected into the second conduit and formation fluids are removed by the first conduit or tubing until steam communication is established between the two intervals.   Once steam communication is established between the intervals, steam injection is ceased and a thermal packer is placed around the tubing so as to form two separated, spaced-apart, perforated intervals.      Thereafter, steam is injected into the reservoir via one interval and hydrocarbonaceous fluids are removed at the other interval.

Title: Atrial defibrillator and method for setting energy threshold values
Inventor: AYERS GREGORY M
IPC: A61N1/38
Filed: 1994-01-04
Granted: 2001-04-17
Abstract: An implantable atrial defibrillator cardioverts the atria of a patient's heart and determines the quantity of cardioverting electrical energy required for cardioverting the atria of the patient. The atrial defibrillator includes a detector for detecting atrial activity of the heart and an atrial fibrillation detector for determining when the atria of the heart are in fibrillation. A delivery stage is selectively operable in a test mode for applying fibrillation inducing electrical energy to the atria when the atria are not in fibrillation for inducing fibrillation. When fibrillation is induced, the delivery stage repeatedly applies test cardioversion electrical energy to the atria until the atria are cardioverted.      Thereafter, a value indicative of the quantity of the test cardioversion energy last applied to the atria is stored for future reference when the atrial defibrillator is in a normal operating mode.
